'35' because it's going to be the 35th major release of Boost.
As I said in my other post - which hasn't generated much interest - I think
that we're at a point where the lock-step approach is no longer feasible;
that is, we can no longer afford to avoid versioning libraries by way of
pretending that the leading 1. in front of the release number makes it a
Put differently, what I'm saying is that Boost can no longer pretend to be a
library instead of a compilation.
A release should merely be a collection of library versions that have been
tested together and known to work.
In terms of SVN structure this could look like:
but of course other arrangements are possible.
The benefit of this approach is decentralization. The maintainer of foo only
modifies trunk/boost/foo, trunk/libs/foo and creates versions/foo-* when
he's satisfied with the test results on the trunk. The release manager of
r35 only copies library versions from versions/ to releases/r35, does
whatever needs to be done to resolve test failures by nagging the
maintainers to fix bugs in foo-2.0 creating foo-2.1 (and failing that picks
1.1 instead), and ships when he's satisfied with the test results on r35.
It's clear who can commit, where, and when, and a release doesn't block
development. It's even possible for r36 to appear before r35. :-)
